PHP获取所有扩展及扩展下的所有函数签名生成php.snippet

<?php
$ext_info = array();
$modules = get_loaded_extensions();
foreach ($modules as $module) {
    $functions = get_extension_funcs($module);
    if (empty($functions) || !is_array($functions)) {
        continue;
    }
    foreach ($functions as $fun) {
        $reflect = new ReflectionFunction($fun);
        $params = $reflect->getParameters();//获取函数参数信息
        $param_str = '';
        $param_num = 0;
        if (!empty($params) && is_array($params) && count($params)>0) {
            foreach($params as $key=>$param) {
                if($param->getName() !== '') {
                    $param_str .= '$${'.($key+1).':'.$param->getName().'}, ';
                }
                $param_num++;
            }
            $param_str = substr($param_str, 0, -2);
        }
        if (empty($param_str)) {
            echo "snippet $fun\n";
            echo "\t".$fun.'('.$param_str.')${1}'."\n";
        } else {
            echo "snippet $fun\n";
            echo "\t".$fun.'('.$param_str.')${'.($param_num+1).'}'."\n";
        }
    }
